SPECIFICATION forming part 0f Letters Patent N0. 601,215, dated March22, 1898. Application led October 5 1896. Serial No. 607,972. (Nomodel.)

To all whom t may concern:

Be it known that CHARLES T. SrnrsoN, deceased, late a citizen of WestHanover, in the county of Plymouth and State of Massachusetts, didinvent certain new and'useful Improvements in Hose-Looms or Machines forMaking Tubular Fabrics, of which the following, taken in connection withthe accompanying drawings, is a specification.

v This invention relates to hose-looms or machines for the production oftubular woven fabrics; and it lconsists of certain improvements in theconstruction thereof, as will be hereinafter fully desc'ribed,landpointed out in the specification and claims connected hereto. y

This invention is illustrated in the accompanying drawings as follows:

Figure lis a plan view. Fig. 2 shows on the left of a vertical centerline a vertical section on the dotted line l and l in Fig. l. On theright of the center line it lshows a vertical elevation. Fig. 3 is avertical elevation of the outside of one of the shuttles, looking towardthe center of the machine. This view shows the top edge of the frame ofthe machine A,

the grooved or double conical rollers in which the shuttle is guided,thelling-thread-tension device, weave-pin, and beating-in hook. Fig. 4 isan end elevation of this same shuttle, but showing also a section of thecentral drivingshaft E of the machine, the stationary gear Gr,

the driving-arm F, which is attached to a faceplate fastened to theshaft E, and the two small gears g' and g2, meshing into the stationarygear G and giving a rotary motion to the driving-Wheel s6, which in turndrives the small wheel S5 fastened to the shuttle. This view also showsthe upper part of the stationary central shaft U, weaving cone T, andrelative position of the weaving-*point and spreader thereto. Fig. 5 isa plan View of a section of the central hollow'shaft, the stationarygear G, the driving-arm F, and the small gears and wheels fortransmitting power to the shuttles. Fig. 6 is a plan view of one of thesegments of covering-plates for the top of the main frame A and whichacts as a guide for the warp-threads, which are reciprocated back andforth by the heddles in the radial slots shown in this plate. This plateis designed to prevent the warp-threads from being carried along by theshuttles in the direction of their movement and thereby becoming en-`tangled one with another. Fig. 7 shows a plan and vertical sideelevation of the tension devices n, consisting of a pivoted guideleverthrough eyes in the end of which a warpthread is passed and a springfastened to the stand supporting this pivoted lever and pressing upagainst a presser-linger interposed between the ends of this spring andthe fulcrum of the pivoted lever, so as to bear ,upon the warp-threadsat this point.

ThisV device consists of a main annular frame A, which is supported onthe legs B and supporting above it the take-up frame O. Passinghorizontally through the annular frame A are the heddle-frames D, whichare actuated by means of the rods d, connectinglinks ol', double-throwcranks D2, which in turn receive their motion through the Verticalshafts cl3, by means of the gears d4 and the gearv d5, which is keyed tothe main shaft E of the machine. This main shaft in turn receives itsmotion through the bevel-gears e and e2 and the driving-shaft e4. On topof the main frame A are three shuttles S S S2, the last-named shuttle S2being shown in dotted lines in Fig. l for sake of clearness ofillustration of the shuttle-actuating mechanism beneath. These shuttlesare guided in their annular path around the top of the frame by thegrooved rollers R, whose shape is that of two truncated cones joinedtogether at their smaller ends. On top of the shuttles S, S', and S2 arethe bobbin-carriers s', which carry the bobbins s2, tension-rollers s3,and weavingpoints s4. These shuttles S, S', and S2, which are three innumber, receive their motion through the medium of the rollers S5 ands6. The rollers s6 are carried by the arms F,

formed integral with the frame F2, which is secured to the annular plateFf, keyed fast tothe main shaft E, before referred to. The arms Frevolve with the main shaft E from left to right, and the rollers s6come up be- IOO the warp-threads between the rollers 35 and SG. Theserollers s" receive a rotary mot-ion by means of the gears g and g2, thegear g2 being in mesh with the large stationary gear G, which is securedfast to the top of the annular frame A. rlhe frame orstand Il, whichcarries the small vertical shafts d3, is also secured to the mainannular frame A. The take-up rollers J and J receive their motionthrough the gears K and K2, the gear K being actuated by means of theworm-wheel 7c3 and worm 7d, which is keyed to the shaft 7&5, which is inturn driven through the bevelgears k and k7, which latter in turnreceives its motion through the vertical shaft L and ruiter-gears Z andZ2, which latter gear receives its motion from and is keyed fast to theshaft c". The take-u p shaft L5 is also provided with a hand take-upwheel m and engaging clutch-face ym, which meshes with the face of asimilar clutch-face m", which is an integral part of the bevel-gear k6.The engaging clutch-face m is held in contact with the oppositeclutch-face m2 by means of the spring m3. The gear 7n is not keyed tothe shaft lo, but drives through the medium of the clutchface m, whichis splined upon the shaft 755 and has a lateral motion upon this shaft.

Upon the lioor between the the legs B are the warp-tension andcontrolling devices comprising tension-frames N, which carry thetension-lingers n, which are preferably constructed as a pivoted lever0L,through eyes 112, in both ends of which the warp-threads are passed,and the tension is produced by a spring u underneath this lever bearingup against the warp-threads. These levers are pivoted, so as to insuretheir being kept in line with the axis of the warp-threads. Thewarp-threads O and O come up through the floor beneath the machine, passthrough the tension-fingers n up over the take-up rods P P2, downbetween the rods P2 and P3, through the take-up weight Q, over the rodP3, under the rod P1, then up through the eyes in the heddles dfin theheddle-frames, then through slots in the guide-plates a, (see Fig. 6,)which form the top to the annular frame A, passing either side of theshuttles S and S, being distended on the outer side, so as to clear thebobbin s2 by the spreader 57. The point of this spreader is designed toenter between the opening of the warp-threads in advance of theshuttles, force them apart, so as to preclude their catching upon anypoint of the shuttle,and to allow them to fall back in place over thetail of the spreader, as shown, and so to the weaving-points s1, wherethey are brought in contact with the weaving-pin T, which is carriedbythe internal rod U, inside of the revolving shaft E.

The illingthreads O3 are wound on the bobbins .S2 and pass through theguide-eyes s, guide-eyes s", tension-wheel s3, and so to theweaving-points sl, where they are forced in between the warp-threads Oand O', the fabric being drawn upward by the take-up rollers J and J2.There are `three sets of shuttles and shuttle-driving mechanisms, asdescribed above, and sixv sets of hcddlcs working in alternate orderwith the set of heddles immediately preceding and succeeding them. rlheobject of the design of this machine is to so construct a machine thatall of the reciprocating parts occupy as low a position as possible andalso to make them as direct acting and compact as possible, so as toboth concentrate and lower the center of gravity of the machine, therebyinsuring its stability and permit of its being run at very high speedwith a minimum amount of jar and oscillation. 'lo insure this result,the heddles, heddle-actuating mechanism, main driving mechanism,warp-thread take-up,and tension are all placed below the path of theshuttles, there being nothing above the horizontal line of the shuttlesexcepting the takeup frame C and its mechanism, which is made as lightand simple as possible, so as not to carry much weight up into the airand also so as to present the least-obstructed view and freest means ofaccess to the weaving-point of the fabric being constructed, which istherefore at all times easily accessible for the inspection of theperson in charge of themachine. It is also designed to accomplish, bythe use of the three or more shuttles, a machine which will form tubularfabrics of comparatively small diameters with the utmost rapidity. Infact, the whole design of the machine is to secure one which can be runat the highest possible speed and produce the greatest amount of fabricin a given time.

Having thus fully described the construetion and method of operation ofthis machine, what is desired to be claimed and secured by LettersPatent is as follows:
